This course has been designed to provide participants with didactic and clinical continuing education to be eligible to administer nitrous oxide (N2O/O2) in the state of New Hampshire. The course will cover the history of nitrous oxide, neurophysiology of pain and pain control, patient assessment including medical and dental indications and contraindications, anatomy and physiology, pharmacology of nitrous oxide, emergency prevention and management, nitrous oxide armamentarium including safe assembly and handling of gas tanks, masks, tubing, scavenger and monitoring equipment, techniques, record keeping, and regulatory/legal issues.

The NH board requires a minimum of 8 didactic hours and 6 clinical hours.

If a course participant is seeking certification in nitrous oxide administration in a state other than NH, it is the responsibility of that participant to contact the appropriate state board and gain knowledge of and meet the requirements for nitrous oxide administration in that state.

This is a hybrid course with self-paced online modules. Once the online portion is completed, the clinical portion would be scheduled with the instructor to join an on campus lab currently in progress with the Dental Hygiene Seniors.

REFRESHER Fact Sheet 2025

This hybrid course was prepared for dental hygienists who have been out of practice for a time and want to get back into the field or for those who are practicing, but feel their skills need updating.

The course is designed to review theory and techniques learned in dental hygiene school and on the job. Current “best practices” will be introduced, but specialized procedures will not be covered in great detail and, in some cases, will require additional courses.

Program Goals:

• Dental Hygiene Process of Care
• Definitive Oral Prophylaxis
• Radiographic Techniques
• Review of Current Center for Disease Control (CDC) Guidelines
• Review of Hand Instrumentation including Ultrasonics

Course objectives are met through didactic and clinical instruction which will introduce, update, and review current techniques in the practice of dental hygiene.

Program Outcomes: 

Participants who complete the course can be assured they have had the opportunity to learn the most up to date, science-based theory and techniques. The program satisfies the criteria of the NH Board of Dental Examiners when a refresher course is mandated for hygienists who want to renew their active dental hygiene license. 

Program Description: (20 CEUs)

• Online Assessment and Review of Theory (2)
• Clinical Review (18)
  • 3-hour lab session to review hand instruments and the ultrasonic tips on a typodont
  • 4-hour clinic session
  • 2-hour radiology review

The online portion needs to be completed before the start of the scheduled hands-on sessions. 

The scheduling of this course will be based upon faculty availability. Students are expected to provide one client for the clinical portion of the course.

Materials:

Students will need a variety of Gracey curettes, scalers (universal, sickle), and a typodont to practice instrumentation. Instrumentation is to be practiced weekly on a typodont. If needed, instruments may be available on a loaner basis (for an additional fee). 

Also required for the course: scrubs, lab coat, loups/light if you have them, scrub cap, proper leather or pleather clinic shoes, and two pairs of safety glasses (one for student, one for patient). Gloves, masks, and face shields will be provided for refresher course (NO latex - NHTI’s clinic is a latex free environment).

Prerequisites and required documents:

• Current CPR Certification
• Liability Insurance
• College Transcript

Please email to:  nhtiwe@ccsnh.edu

*PLEASE NOTE: You will NOT be officially registered until ALL paperwork as well as payment has been submitted.

On-line lectures and learning activities are coordinated with laboratory practice to develop dental radiographic techniques. Students are required to schedule two clients. Techniques covered include: digital radiography, processing, mounting and evaluating films. Emphasis placed on client and operator protection, exposure and processing errors, asepsis protocol, radiographic techniques and equipment function. Following completion of the course, you must pass the DANB-Radiation Health and Safety exam before you are eligible to expose radiographs in your office. This requirement is according to the NH State Board of Dental Examiners Rules and Regulations. NOTE: This course does not meet the radiology course requirements for the NHTI Dental Assisting or Dental Hygiene programs.

Online portion: *May 5 - June 27, 2025
